No. That's not right. PPro and newer support 36 bits of physical
address, which leads to a max size of 64G. The biggest Mobo I've seen
for x86 is 8GB (and that was second hand info about a micron server
mobo). FreeBSD can't go above 4G w/o rewriting all DMA customers to
use bus_dma, which are the network drivers iirc. The pmap layer would
also require a fair amount of work as well. But I drift from the
charter of this group now :-)
